This is the very first release of a driver for X-Box gamepads.
Basically, this was hacked away in just a few hours, so don't expect
miracles.
+
In particular, there is currently NO support for the rumble pack.
You won't find many ff-aware linux applications anyway.
-0. Status
----------
+0. Notes
+--------
-For now, this driver has only been tested on just one Linux-Box.
-This one is running a 2.4.18 kernel with usb-uhci on an amd athlon 600.
+Driver updated for kernel 2.6.17.11. (Based on a patch for 2.6.11.4.)
-The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) reports
-8 axes and 10 buttons.
+The number of buttons/axes reported varies based on 3 things:
+- if you are using a known controller
+- if you are using a known dance pad
+- if using an unknown device (one not listed below), what you set in the
+ module configuration for "Map D-PAD to buttons rather than axes for unknown
+ pads" (module option dpad_to_buttons)
-Alls 8 axes work, though they all have the same range (-32768..32767)
+If you set dpad_to_buttons to 0 and you are using an unknown device (one
+not listed below), the driver will map the directional pad to axes (X/Y),
+if you said N it will map the d-pad to buttons, which is needed for dance
+style games to function correctly. The default is Y.
+
+dpad_to_buttons has no effect for known pads.
+
+0.1 Normal Controllers
+----------------------
+With a normal controller, the directional pad is mapped to its own X/Y axes.
+The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) will report 8
+axes and 10 buttons.
+
+All 8 axes work, though they all have the same range (-32768..32767)
and the zero-setting is not correct for the triggers (I don't know if that
is some limitation of jstest, since the input device setup should be fine. I
didn't have a look at jstest itself yet).

play first person shooters with a pad. Your mileage may vary.
+0.2 Xbox Dance Pads
+-------------------
+When using a known dance pad, jstest will report 6 axes and 14 buttons.
+
+For dance style pads (like the redoctane pad) several changes
+have been made. The old driver would map the d-pad to axes, resulting
+in the driver being unable to report when the user was pressing both
+left+right or up+down, making DDR style games unplayable.
+
+Known dance pads automatically map the d-pad to buttons and will work
+correctly out of the box.
+
+If your dance pad is recognized by the driver but is using axes instead
+of buttons, see section 0.3 - Unknown Controllers
+
+I've tested this with Stepmania, and it works quite well.
+
+
+0.3 Unkown Controllers
+----------------------
+If you have an unkown xbox controller, it should work just fine with
+the default settings.
+
+HOWEVER if you have an unknown dance pad not listed below, it will not
+work UNLESS you set "dpad_to_buttons" to 1 in the module configuration.
+
+PLEASE if you have an unkown controller, email Dom <binary1230@yahoo.com> with
+a dump from /proc/bus/usb and a description of the pad (manufacturer, country,
+whether it is a dance pad or normal controller) so that we can add your pad
+to the list of supported devices, ensuring that it will work out of the
+box in the future.
+

1. USB adapter
--------------
Before you can actually use the driver, you need to get yourself an
-adapter cable to connect the X-Box controller to your Linux-Box.
+adapter cable to connect the X-Box controller to your Linux-Box. You
+can buy these online fairly cheap, or build your own.

-device) with the only difference in a nonstandard connector (5 pins vs. 4 on

+2. Driver Installation
----------------------
Once you have the adapter cable and the controller is connected, you need
to load your USB subsystem and should cat /proc/bus/usb/devices.
There should be an entry like the one at the end [4].

+ RedOctane Xbox Dance Pad (US), vendor=0x0c12, product=0x8809
-If you have another controller that is not listed above and is not recognized
-by the driver, please drop me a line with the appropriate info (that is, include
-the name, vendor and product ID, as well as the country where you bought it;
-sending the whole dump out of /proc/bus/usb/devices along would be even better).
+The driver should work with xbox pads not listed above as well, however
+you will need to do something extra for dance pads to work.
-In theory, the driver should work with other controllers than mine
-(InterAct PowerPad pro, bought in Germany) just fine, but I cannot test this
-for I only have this one controller.
+If you have a controller not listed above, see 0.3 - Unknown Controllers
If you compiled and installed the driver, test the functionality:
> modprobe xpad
> modprobe joydev
> jstest /dev/js0
-There should be a single line showing 18 inputs (8 axes, 10 buttons), and
-it's values should change if you move the sticks and push the buttons.
+If you're using a normal controller, there should be a single line showing
+18 inputs (8 axes, 10 buttons), and its values should change if you move
